What is 2/6 + 8/9?

Here's how we add

2

6

&plus;

8

9

Step 1

We still have different denominators (bottom numbers), though, so we need to get a common denominator. This will make the bottom numbers match. Multiply the denominators together first. Now, multiply each numerator by the other term's denominator.

Now we multiply 2 by 9, and get 18, then we multiply 6 by 9 and get 54.

Now for the second term. You multiply 8 by 6, and get 48, then multiply 6 by 9 and get 54.

This gives us a new problem that looks like so:

18

54

&plus;

48

54

Step 2

Since our denominators match, we can add the numerators.

18 &plus; 48 = 66

That gives us an answer of

66

54

Step 3

Can this fraction be reduced?

First, we attempt to divide it by 2...

Are both the numerator and the denominator evenly divisible by 2? Yes! So we reduce it:

66

54

÷ 2 =

33

27

Now, try the same number again.

Nope. Try the next prime number, 3...

Are both the numerator and the denominator evenly divisible by 3? Yes! So we reduce it:
